铁路隧道监控量测实施及数据分析

摘要

大回山隧道洞身穿过断层破碎带施工过程中拱顶出现下沉现象，通过监控量测数据分析，改善施工工艺，有效抑制了拱顶下沉速率，从而指导隧道施工的掘进速度和支护时机，确保了隧道施工的安全性。%〔Abstract〕 Construction of Dahui Mountain Tunnel which passes through fault fracture zone has the arch appear subsidence phenomenon. Through the monitoring data analysis, it is to improve the construction process, and effectively inhibit the vault subsidence rate, so as to guide the tunnel construction speed of driving and supporting time to ensure the safety of tunnel construction.
